INTERDEV NOT SAVING MY WORK!

I’m running Interdev 6.0 on W2K Pro, I’m working on my project locally in master mode. Whenever I make any adjustments to any DTC control, for some reason Interdev will not save any of my changes. The strange thing is it’s a random situation. Theonly way to get it to save it if I’m lucky is to close out Interdev and reload the project and hope that it’ll prompt me to save my work.
