Meterpreter strange hang

[mmo at remote-exploit.org (max moser)]

Hi there,

well i did use Meterpreter from Framewaork 2 with great success ,  
thanx for that. Now during the development of the next backtrack  
release i tested the version from framework 3 and had an ugly situation:

When meterpreter reverse payload .exe (made using payload) is  
executed (On winodws XP) , it connects to the payload handlier  
correctly, upload is successfull and then it hangs, sometimes it gets  
to the point where it tells that it has opened the connection. but  
then it hangs and no meterpreter prompt.

It is in a local lan, infact just Windows with vmware inside running  
backtrack.

Any ideas why this happends?

Greetings

Max
