UIStudio lockup

Docking/MDI for Windows Forms Forum

Hi,
I have just had UIStudio lock up when moving a window to dock as a tab on a floating toolwindow. The "guides" on screen appear as normal windows titled "DockGuideForm" rather than their normal appearance.
Stack trace if breaking in looks like this:

Can you give exact steps to duplicate it in the sample project? I can't repro it here so far.

Can reproduce (hard without screenshots though):

Run sample app.
Drag and Float "Tool Window Properties"
Drag "Dock Manager Properties" tab inside "Tool Window Properties" so it is docked beside "Tool Window Properties". i.e. two tabs are now side by side in an untitled window.
Press Auto-Hide for "Tool Window Properties" - auto-hides on main app frame.
Press Auto-Hide button again for "Tool Window Properties" - docks to main app frame.
Drag "Tool Window Properties" and attempt to dock as tab within floating window ("Dock Manager Properties")
Boom!

I'm still not able to dupe any problem. I'll try and have some testers check it out as well.

BTW, you found a bug too. The auto-hide button should not be visible on floating window title bars. :)

I had two other customers try to duplicate it and they have been unable to cause it to break either. Are you able to duplicate it another way since the next build will no longer have auto-hide buttons in the floating windows anyhow.

Havent seen it happen any other way. I mailed in screenshots with each step - has anyone tried to reproduce the problem using those?

Actually I was doing the same things as in your screenshots based on your original posting. Anyhow, like I said, that functionality is no longer available after the next build since it never should have been there.

The behaviour did seem weird, so that's fine.
Can you give me any idea on a ship date for a fix?
We are nearing a release for our software and this seems like quite a serious bug since it takes 100% CPU
as well as rendering the app useless...

I would think in the next week or so. We've seen a couple cases where Microsoft's code goes into infinite loops now. Although this is one we haven't run into before. Another one is one with SelectNextControl which can lock up an application and we've had to work around that bug. What .NET framework do you run by the way?

We're using version 1.1
The latest build of this product (v24.1.0) was released 2 months ago, which was after the last post in this thread.
