Hi all,

Here is my extremely strange issue. It is a little long-winded so please bear with me.

 

I installed Lion on a 40GB partition of my 2.66Ghz 24" iMac just after its release a couple of months ago using Bootcamp just to give it a try. Yesterday I booted into Lion and ran all the updates. No problems thus far. All the updates installed and it runs fine. However, when I rebooted into SnowLeopard (my main OS) the finder is all funky. When I try to open more than one window or two pieces of software the other one disappears from the desktop into some sort of cyber void. Also, when I restart it boots to the disc select screen with three options, Snow Leopard, Lion or the Lion recovery disc, which seems to be a base system built in to Lion. I tried running the disc repair utility on the Snow Leopard drive from the Lion recovery disc, which came up with no errors. I have run the permissions repair and Onyx in Snow Leopard. I deleted a few preference files and forced quit the Finder a few times, but it still is funky. It has me bewildered! I can only reason there is a conflict between running the two versions of OSX and somehow the Lion Recovery disc and/or updates have interfered with Snow Leopard.

 

Any ideas? I am tempted to delete the Lion partition with Bootcamp to see if it fixes the problem, but fear the damage has already been done to Snow Leopard. I could do a restore from Time Machine, but I would like to know if there is a connection between running the two versions of OSX.

 

Any input most welcome

Thanks in advance
