Hi,
To reproduce this problem I've done the following test:
Save values in the file "test.test.test test.DAT", load this file, changed something, save and load again. This works fine and without any problems.
I'm working with DIAdem 8.10 and XP as OS.
If you can reproduce the problem with DIAdem 8.10, please send me an example file so that I can do some additional tests.(Therefore you can use the following email address walter.rick@ni.com)
I hope this will help you.
Regards
Walter
