Search problem-greek language

[gkomnin]

I have installed sugar ver 4.2.0d (i think so) in a machine running Windows 2003 server,mysql 5.0,apache 2.
The problem is that although i can search when i use latin characters i cant when i use greek characters.
The greek charaters are shown normally and i can also can write greeek.
When i write something in greek to the search field and try to search it the result is :
[Please enter at least one letter or number for your search ...]

I have seached the forum and have found a similar problem (search non latin) but the solutions provided dont work for me or i have done something wrong...
any suggestions?

What is the code page (collation) that you are using?

In my version 4.5.1 i can search without any problem with the greek characters.

I have also installed 451 from scratch and it works fine..the problem is that i had installed sugar 4.2.0a in a server and it was necessary to update the mysql database to version 5.0.The problem appeared after the mysql upgrade.
