Bearcat, I am rather happy with Ubuntu 64-bit (currently 9.10) but honestly I have never tried another distro. I am using it since 8.04 if I remember well and I have never had any major problem.
Good GUI, seriously and simply maintained and upgraded and if you have Windows partitions that you wish to keep it reads and writes NTFS and FAT without trouble.

I installed it in dual boot over an XP 32 and I can use my OpenOffice files and manage my mail (with Thunderbird) from both sides.

It needs a bit of learning when you start to want to tweak things your way, but I think it would be the same (or worth maybe) with other distros.

Good luck. Jean.

Ubuntu hands down.
I use Ubuntu everyday on my work computer and my home computer and I would not change that for nothing.
Don't buy windows, its a waste of money.

Think it was BobCat13 who reminded me few days ago of the solution for:

[error] App version has unsupported platform xxxxxxxxxxxxx

if that is what you're talking about... guessing with the limited amount of info provided.

edit: also, knreed just posted here

to confirm, if this is the exact problem, that there's a fix in the alpha client 6.10.33. Wait till the formal recommended release is out or apply the cc_config.xml work around referenced above.

Bearcat,

that's why we ask always to post the messages to not leave us guessing. The ca-bundle.crt problem is an entirely different / additional one you get, but at least it confirms the client is now being recognized with the correct platform info. Some Linux distro's do not install this properly or completely omit it. There are different ca-bundle messages, so look in the FAQ index for the one applying to you and use the recommended way to fix.
