Many thanks to Daniel Mills for suggesting I check my temporary file
accumulation. It appears that my code was not closing queries and I had
built up to the limit of 10,000 temp files. So, if your Pro starts acting
oddly, do a search (with show hidden files) for file starting with "~MAP".
Closing the application process resulting in these files not being cleaned
up.

Suggestion for MapInfo - how about an error message when Pro cannot get an
available temp file name?

Subject: MI-L Pro crippling problem


Hello -L'ers,

Here's a nasty problem that I found this week and have not yet been able to
solve.

On a client's computer (Win2000), I was running a MB program (compiled with
4.5, running on 6.0) which runs through a large table and splits objects
that cross international boundaries. The program uses "fastedit on undo off"
for speed. The process is one that Pro seems to slow down Pro as it
progresses. I didn't check memory consumption but I have found such problem
in batch object processing in several versions of Pro. Anyway, the program
seemed to have hung so, checking there was no disk activity, I shut the
process down. Then things went wrong... 

On the system there were three version of Pro v4.5, v6.0 and 7.5. Versions
v4.5 and v6.0 now crash on start-up (get past splash screen, see main window
with menus and toolbars, hourglass pointer, and that's it - doesn't get to
the start-up dialog). Version 7.5 seems to work OK but when I do a SQL
select on any table, it hangs (again with an hourglass pointer). I thought
this could be table damage or (heaven forbid) a disk error, but after lots
of check it seems to be neither.

I moved on to another system the next day, this time WinXP (SP1), and the
same thing has happened.

On both systems, the clients IT staff have deinstalled everything and
reinstalled and there is no change. It seems I have cursed both machine
never to run Pro again.

Anyone seen anything like this before?
