Mendix and windows 8 / 8.1

Is mendix (4.5.2 and above) compatible with windows 8 / 8.1? It seems that mendix is much slower on 8.1 then it was on 7. Especially the rename or duplicate action seem to be harder for mendix on the windows 8.1 edition. Is this a known issue for mendix and do we need to downgrade to windows 7 again? Anyone dealt with some of this issues already?

Hm,,, ?
Mendix Modeller is hosted by Java Virtual Machine (JVM) uses Java runtime libraries. This is rather interesting question: does JVM has issues running on W8.1 ?

It appears there is a problem with Java networking under W8.1.
