Hi LesThere will be a new new version (4.01) hopefully later today. This addresses an issue that came up on some ( a few) user's PCs because of interaction with another 3rd party program. All will be explained in a message to the opt-in list later day.
It is possible that the problem is related to what you're seeing Les, so you might want to try the 4.01 version as well.
I checked what causes that message in the compiler that you saw.
The only situation that exact message is generated is when we ask Windows to File Copy, and it fails to copy the "stub" to a temporary file.
The stub is EVIEW.DAT. So on your system should be something like C:\Program Files\Activ E-Book Compiler 4.00\EVIEW.DAT
The temporary file will depend on your system, but it will be in the temp location... something like C:\TEMP\ or C:\WINDOWS\TEMP etc.
If you open an MS-DOS window, and type SET at the C:> prompt, it should tell you, probably where your TEMP files are.
So basically my advice is
1. Read the announcement about 4.01, which hopefully should be later today.
2. See if the problem happens with 4.01
3. If it does happen, check the TEMP path as above. You might also want to
- empty your recycle bin
- if all your files are on one big drive, and you are PC-comfortable enough to do this, then try setting the Windows swap file size to a fixed size in Windows control panel. Sometimes the swap file has a habit of growing and growing and suddenly eating up most of your disk space.
