windows 10 crashing

[stubbie]

hi guys, my wife has yowindow on her pc and I recently updated to win10 on her machine, I have been using it for some time myself
and have worked out so of its little grumbles, but yowindows was removed as saver on install
I have updated it to the latest version but still bs every so often, it could be a driver issue, but I have
now tried a AMD Radeon HD 7500 series (1GB) PCIe x16 Graphics Card and a similar Nvida card
and both still crash. any idea im getting loads of ear ache guys

Make sure Flash player works in Internet Explorer.
Otherwise YoWindow will not be able to work.
Windows 10 is in BETA so Flash Player may not work as expected.
I remember similar issues with Windows 8.
