Hello,
Good job, DF seems faster then previous versions and with no apparent mouse freeze or lag.
About bugs, today I noticed a rather strange behaviour by DF. I had around 20 (!) DF processes running. I closed it and executed it again and there were 3 processes. Every time I start the programme I get 3 processes where it should only be one, as if it executed DF's main executable 3 times at each run.
The other two processes use around 1MB of memory and can be killed without any problem.
EDIT: Funny... now there are only 2.
I was wondering - I just noticed this myself, so I went exploring - and I noticed in my Add / Remove Programs (aka Programs and Features in W7) that I had 2 instances of DF - the stable as well as the Beta, and I remembered what you had written about needing the beta installed on a machine clean of previous installs - I thought it might have had something to do with that....
Glad to know it is fixed for the next release.
I am I.
I hate to add to a topic marked complete, but Jon, you need to see this....
On starting / restarting my computer, I get a few instances of the DF hook - and this is with Beta5.
The screen shot is taken with Sysinternals' Process Explorer view, and I am running Windows 7 RC x64.
Want me to enabled the debug mode?
I am I.

OK, I had just started DLing 106, but I canceled that install and I'll do those for ya.
I am I.
OK, gonna reboot and see if I have the same error on reboot - also I have Integrity level enabled - but only (apparently) when I am 'viewing all processes from ll users' - go figure lol....
Back in a sec with an edit and a new screen shot and debug log.
Update I rebooted after enabling debug logging - and the 105 only has a single instance this time.
I suspect it is hit or miss - so I'll continue to play around to see if I can reproduce it, leaving the logging on.
Or would you rather I go ahead and upgrade to 106 and *then* test?
I am I.
I am using beta 6 and right now there are two instances of DisplayFusionHookx86.exe running.
