546057 - [OOPP] Silverlight demo completely locks browser. Killing the runtime process doesn't always help

Status: RESOLVED WORKSFORME

(Plugins Graveyard :: Silverlight (Microsoft), defect)

Description

[u88484]

Attachment: Screenshot

This Silverlight demo completely locks the browser and killing the runtime process doesn't always help

STR:
1) http://www.e-naxos.com/slsamples/lorem/loremgen.html
2) Hit the 'Generate' button twice
3) Hit the 'Copy All' button
4) Browser locks

A box does briefly pop up after hitting the copy all button and it seems to steal complete focus from Firefox (can't even close it).  The only way to again see the box is the mouse down on the taskbar preview.

Took me four times to file this report due to Firefox crashing with the demo running in the background without me doing anything on it so there might be more to that demo but I'm using an hourly and don't have a stack.

After reproducing at least 10 times I actually got the demo to somewhat correctly work without locking up.  The box is supposed to say "The clipboard isn't available in the current host."

Looks like a dupe of bug 544893?

Doesn't lock up here, but I don't see any user input getting to the demo. Even though the events are being delivered over ipc.

[u88484]

Jim, the user input is inside the demo.  I can't reproduce all the time but my steps are what I did most of the time to hit this bug.

[Jim Mathies [:jimm]]

I think the hang has been fixed, but we still have silverlight input bug 547353 that's getting in the way.
