Using Windows 7 Ultimate 64bits. Tried all browsers.
This happens on 1 of the .capx I have after I installed the new r88.
When I preview the game I'm getting these error screens, if I click OK or close, another one pops up. The game appears to advance 1 frame after closing and before a new message appears.

If I check the box that says "Prevent this page from creating additional dialogs" the game continues normally but a little different than it used to. For instance on Chrome it appears to work normally but the collisions are a bit off, on Firefox the sprites don't move at all (8 Direction behaviour).
