hi, 
i need help. if there is anybody who could help me please do it. is it possible to cache a buffer? i want to do the following: i want to cache a bigger part of data (from a framebuffer update 1024x768x2 bytes for example). in the way i do it now it is much too slow everytime i click to look at the data it starts to get the data from the beginning on ...40seconds waiting ...next click ...40seconds waiting... and so on. it is annoying. thanks for your help. 
best regards from germany christian
