When I try to rework my slideshows to the newest version of Muse, it crashes completely when I try to resize the caption box by dragging any side of it. I am using it on a Windows 7 PC. It also is acting very sluggish. The new version is useless and aggravating this way. and how can I revert to an older version while you clean up this mess.
Apologize for the problem, We have already logged the bug actively working on this issue.
If Your using the full screen slide show then this issue will occurs ie: when you resize the caption muse will be crashed.
Workaround: If your not using the full screen slide show please delete the complete slide show and recreate the slide show, this solution should work for other slide show.
