I'm having the same issue reported here: www.binaryfortress.com/Forum/index.php?topic=2483

Sometimes it takes a full minute for text I type to show up in the Microsoft Lync conversation window. I just today realized that it might be related to DF, so I disabled everything in the compatibility settings, and now the application is performing as expected.

I'm using 3.4.0 beta 3. Is there any way I can help you troubleshoot this?

OK, cool. Let me know if you need any testing help.

Actually, this may be more related to title bar buttons than the hooks. I'll keep you posted with anything I find out.

Interesting, I have Microsoft Lync 4.0.7577.275 and have noticed a slight slowdown as well. For example, when I click on a name to open the chat dialog, the form opens, but no controls will display until after the Display Fusion Title Bar button displays. (see attached video for example) The delay is only slight in my case (I have also attached a video without Display Fusion with Lync for visual comparison). Also, the Title Bar Button will tail behind the window when dragging (this is rare); up to 100px away or more, but other times not at all.

Let me know if I can provide any other info.

I've been running with hooks enabled for communicator.exe for a number of days, but title bar buttons disabled, and I haven't experienced any slowdowns yet.

Does it speed back up if you disable TitleBar Buttons for Communicator.exe? That's what works for me.

Yes, it does.

I only ever noticed it when I had chat windows open, but then again I almost always have chats open.

I've turned title bar buttons back on in the beta 7 "try 2" build. I'll report back.

I've run it for a day or so with Title Bar Buttons on, with B11 and now B12, and it's going OK. Unfortunately, I'm on vacation for the next two weeks and won't be around my work computer, so how about I update you if I run into any new problems.

Back from vacation and I've run a full day so far with no problems.
