Yes, after a full deinstall and registry clean and deep file clean (IObit uninstaller - has it's issues, so this is no recommendation, just an explanation of what I did!)
On re-install all works, even Matlab, and an 80 waveform into animated GIF, oh, that's cool!
So, there must be something not installing on an upgrade.
Both the PCs (XP and 7x64) had previous Release versions and Beta, Beta was uninstalled either just before or after the final Release version was installed, so while a clean install is OK (no previous versions in place) a dirty upgrade, or post install removal of beta seems to cause issues.
BTW this feature is very good, can't believe I've never heard about it ... or indeed seen any animated GIF's on the forums ... so who can post the most amazing animated GIF? there's a challenge! (of a Pico waveform!!
Thanks for the speedy replies, helped galvanise me to move ahead and hopefully give Pico enough specifics to fix it.
Volrem, can you confirm if a basic uninstall/reinstall fixes the issue?
