Hello Latch!
Thanks for your clarification. Indeed I meant where the code was "interpreted" and am using the original editor. I believe I found the solution to the problem. Normally, as administrator on your computer, you will never have this problem. However, with a restricted log in, the needed rights may be turned off, thereby causing a strange problem where opening different code files all execute the same code (coincidentally, the last code file executed on the admin account).
DBC v1.13 requires permission to write to the C:\WINDOWS\Temp folder (in addition, the new version, DBC v1.21, instead writes to the C:\dbTemp folder). If the restricted log in doesn't have the correct rights, you will get the same code problem. In either case, you need to edit a "Special Permission" for writing to these folders.
As administrator, right click your C:\dbTemp folder (or your C:\WINDOWS\Temp folder if running DBC v1.13) > click 'Properties' > then click the 'Security' tab. Make sure the restricted log in has "Read" and "Read & Execute" permissions.
Now, click "Advanced" to enter the "Special Permissions" editor. Find the "Create Files/Write Data" entry and click "Allow." Now the restricted log in will be able to write to the folder when executing the code.
In short, a VERY specific fix to a VERY specific problem.
Running rings around you.
