My Safari 4 on Mac OS X has been always hanged with pages with Flash

Actually, My Mac mini with Safari 4 always hanged with web pages using Flash or YouTube movies.

After months with nightmares, I found it was caused by the conflict between Safari and SafariStand.

I deleted SafariStand, and I got very smooth web surfing with Safari 4.

My fault was that I do not updated the SafariStand after I installed Safari 4.

SafariStand is installed on /Library/Application Support/SIMBL/Plugins/SafariStand.bundle .

I was mistakenly used SafariStand 3.1T161 with Safari 4.

Current version of SafairStand is 4.0T167 and it is compatible to Safari 4.
