Problems with Log In and Check Outs - IE?

[DrByte]

Maybe it has something to do with the sessions?

Yes.

I don't want to switch recreate session in admin>sessions to false since that'll cause other problems.

Correct.

Could changing:
define('SQL_CACHE_METHOD', 'file');

to
define('SQL_CACHE_METHOD', 'database');

in both configure files possibly help?

No
