I have connected many sequences to menus in the past but have never come up with this problem before. Every .exe file runs properly but when I link them to the buttons on the menu some of the sequences sometimes do a repeat run. Sometimes they return to the menu and sometimes they don't. It seems that every time I run through them that it's a different one which repeats itself and on occasions the whole programme runs through without any repeats. I'm using PTE 7.5, I have scanned the computer for infections/viruses and I have uninstalled a trial version of PTE 8 just in case that was interfering with it. Any suggestions would be gratefully received - I'm desperate!
