Go to the ​user guide online tool (you'll need write permissions there), and do a "Block Edit" of a page. If you then click on a block, it opens a pop-up window. Resizing that crashes WebPositive (full report attached):

Crash when resiting pop-up window

[humdinger]

Seems to be a more general problem: resizing the Web+ window leads to similar crashes. It appears that making the window smaller is OK, but making it larger than the initial size leads to the crash.
