Well, the !Boot file has the line Set NetSurf$Dir in it, so booting an obsolete version will definitely change the system variable. I thought it was recommended that boot files should have that line of the form If = "" Then Set NetSurf$Dir so the variable is only set if it doesn't exist. Only the !run file sets the variable directly. It means the source of various resource files will be set to the old version, e.g. the default CSS styles which may influence the layout of pages. -- Chris Johnson

That's what I would have thought, but I can't see how, when you inadvertantly boot an obsolete version, you get bugs that were present in that version and when you reboot the correct application, without quitting and re-running it, it comes all right again. This is easy to demonstrate. Maybe that particular bug was data-related. The good thing is that I've done a change to SiteMatch which should stop it picking up obsolete data files if the app$Dir variable is accidentally changed. The path is stored on start-up. -- Richard Porterhttp://www.minijem.plus.com/ mailto:r...@minijem.plus.com I don't want a user experience; I just want stuff that works.

I think that ducks the issue. I don't need to have a four year old copy of NS hanging around, and it won't be once I've archived it to the network drive. In fact I don't need to keep it at all but it was there. However I do need to keep other more recent copies of NetSurf, for example the last one or two development versions in case of problems, and the last released version. As for the backup software, I am chasing down problems with SafeStore/ LanMan98/network drive not coping with filenames that contain 8-bit characters and crashing the drive. I don't know why the backup system causes !Boot files to be executed but I had one instance of an error because a filename in a !Boot file did not use the same case as the actual filename, and the network drive filing system is case sensitive. Anyway, given the propensity of RISC OS to boot any old application that it comes across, it follows that running applications should be immunised against this possibility. You didn't answer my question: is it possible for NS to execute old code whilst still announcing itself to be the current version? I assume the answer is 'yes' because running the correct !Boot file corrected the fault without having to quit and rerun NS. -- Richard Porterhttp://www.minijem.plus.com/ mailto:r...@minijem.plus.com I don't want a user experience.

Alternatively, you could fix your back up software (which is clearly broken if it really is at fault), or not have a four-year-old copy of NetSurf hanging around. B.

It's happened again, and I'm backing up files again. I have a theory that might be connected to what occasionally happens in SiteMatch. The directories I copied included old versions of NetSurf and SiteMatch, and it's possible that RISC OS could have booted those applications. Although the info on the icon bar still says "r10951", is it possible that NetSurf is actually picking up obsolete code from the backup file? For certain NetSurf$Dir now points to a Jan 2006 version of NetSurf the backup drive. Is it possible to avoid this situation, for example by storing global variables locally at start-up and not relying on them always pointing to where they should be pointing to? -- Richard Porterhttp://www.minijem.plus.com/ mailto:r...@minijem.plus.com I don't want a user experience.

That's strange because it's not doing it this morning. The site was http://www.minimarcos.org . I don't know what might have affected it yesterday. The only significant thing I was doing was copying a lot of files to a network drive via LanMan98 but that shouldn't have affected NetSurf.

Can you either check this again, or provide a minimum test case? Because none of the changes between these two revisions touch layout.
