[tedtiger]

I've encountered a non responsive Zend Studio 12 64 Bit during a copy and paste operation
Build ID: 12.0.1.v20141117-20141210-1054-293
Windows 8.1 64 Bit

I've made some memory dumps:

first one is right after the start
second dump is during during event
thrid dump is right after studio was responsing again
I've included the support file, too.

Thanks!
I am downloading it and will look at it.

Any news on this? Do you need more dumps?

I am busy right now with completing some important activities before the holidays.

It might be helpful to attach a thread dump (taken during he freeze) - just in case the root cause is not a memory issue, but thread locking.

Ok. How can I do that?

I was able to make some heap and thread dumps for the Copy and Past hanging problem.
I've had 6 projects open and tried CTRL-C operations on different opened files (files were already open after launch).
After the fourth or fifth operation the bug occured (tried selecting single variables and multiline).

The ZIP-File contains a the ZS Support ZIP, 4 heapdumps and 4 threaddumps.
The files with the 0 in the name is before the bug. The 1 and 2 are right after and during hang. Number 4 is after ZS got responsive.

Thanks for dumps! For now I had just time to look at the thread dumps. From your data it looks that freeze was caused by hyperlinking (Ctrl+Mouse Hover) mechanism. It is possible that when you were trying copy/paste something (Ctrl+C/V) you activated hyperlink for part of code and this operation freeze Studio. If you still can reproduce issue can you try just press Ctrl and move mouse over region you tried to copy earlier?

Exactly this is it. I can reproduce it 100%. But it only hangs the first time. I guess some cache is preventing it happening the second time.
But after a while it happens again. Maybe it is possible to speed things up here. The waiting time is a little annoying.

Internally we call it the Zend Studion Mourning Minute. :-)
