Could not start Idea 8.1 on Windows 7 Beta

IDEA 8.1 with Windows 7 Beta (32bit) runs perfect on my lenovo notebook..
Try to reinstall..

After restart, I could successfully open IDEA but it hung up randomly within several minutes of use. I couldn't even use "End Task" to kill IDEA. I checked the log directory. It was generating tons of threadDump text files infinitely. Below is one of the threadDump file. Does anyone have any idea? Thanks!

Where is IntelliJ's log file?

I too am using IntelliJ 8.1 on Windows 7 Beta; it is working for me so far...

-Kay

For the people that IJ 8.1 works on Windows 7, are you logged in as administrator or a normal user ?

I'm logged in as administrator.

I logged in as a normal user. Does it make any difference? IDEA just stopped responding again when I tried to create a new project. I will try again with an administrator account.

It shouldn't but here is my experience...
About a month ago I changed the account I normally use from an administrator to a user. I hit some problems in the .intelliJXXX directories that seemed like permission problems.
I did a recursive change of permissiions & ownership and that cleared up the problems I was experiencing.
