To prevent those problems I did it the following way in the language institute I worked, where severals students had to work with the same QL-program at the same time.
1) There is one original QPC, SMSQ/E.bin and QXL.win on the server. 2) Clicking a QPC-icon on the client's desktop first runs a small batch-file which will XCOPY (DOS command) all files to the client computer and then 3) run QPC from the client computer.
The XCOPY command cares for copying only when something on the server has changed, so you can make sure that changes to programs or data is only done on the server "original" qxl.win file. If changes on the client computers have to be stored, just adapt the XCOPY-batch to not copy QXL.win.
Everything runs fine, fast and complications are not likely. Modern PC-networks are so fast, that you hardly notice the copying.
Umm ... a cool solution, Wolfgang.
You have brought back memories of discovering the use of XCOPY rather than COPY in DOS ... :-)
Your solution should be perfect for Dilwyns' proposal for his small user network.
Because, as you say, the background copying will hardly be noticed.
In fact my experience of using networks is that it is nearly always 'slow' compared to a single machine anyway. So the user is hardly going to be inconvenienced.
