After a month of perfect working, navtweak2.7 stops work. Now I can open navboot with version 2.7 and operate with it, but when I try to save the work then I have a message: navtweak.exe has stopped working.
I use gtk2-runtime-2.16.6-2009-12-01-ash.exe for navtweak 2.7, and gtk2-runtime-2.14.7-2009-01-13-ash.exe for POISoN on Windows 7. These files are in bin folders of the program. I'm using navtweak 2.6 too and there is no problems with it. Does anyone faced with this problem?

P.S. It's full mystery to me. I installed virtual Win XP on my comp and installed GTK+ and Navtweak 2.7. When I run navtweak for the first time, it was able to save modified navboot, but when I tried to work with the program again, the program stopped working during saving the navboot. After that installed navtweak on 2 different comps and the results are the same: first run it works, second-no.
