SEF Advance2008 1.5.6 on Joomla 1.5.4

1) I was using SEF Advance2008 1.3.1 on Joomla 1.5.3 and decided to upgrade to Joomla 1.5.4 and found that Joomfish 2.0 beta does not translate languages anymore on IE7 (but FF is still ok).

2) I also upgraded SEF Advance2008 to 1.5.6 and found that:
    a) Joomfish now does not translate even on FF.
    b) When I disabled SEF Advance the Joomla Admin auto log me off and I have to login again.
    c) The fronpage page title has missing text when using Joomla SEF Patch extended version for 1.5.4.

3) I have also upgraded Joomfish to 2.0 beta2 Public and found the worst case with SEF 1.5.6: front end of Joomfish always stays with the default language (as set in back end) and selecting other languages has no effect.

I wish I had kept Joomla 1.5.3 (with more imcompatilities between SEF 2008 and Joomfish than the latest versions). Now I will have to restore my Joomla site backup before these upgrades !

SEF Advance 2008 will not support Joomfish beta until it's stable.
First then it will be fully supported.
