Such behavior shouldnt correlate with your operating system, since we didnt depend on anything the system generates.
The point, that your working forum now doesnt have any problems with TMS, seems strange, so maybe it is a problem with the TMS beta. I think it is the best to see what happens with the next version, maybe it will solve this, since it doenst use TMS anymore.
If not, i will gladly look at this again.
What i am more interested in at this point is the addon you use to change your forum icons. Can you tell me the name of this addon? I dindt get a repsonse from Popa Andrei until now.
Maybe it is even the same addon giorgino used before (

Since customize each icon per forum is a built in feature of vBulletin, called forum prefix, (which we support since our first version of this addon, cause we use this ourself), using the built in feature solved this matter for giorgino (and reduces the time of maintenance work, since there is one external addon less)
A fully solution can be found here:
