Hi.I have a heavy problem with Creo3.When i create a assembly group, place the first part, it's all ok, but when i add a 2nd, open the place dialog, turn or zoom the whole thing, it crashes my video driver and Creo hangs up.The same, when i use the mini window with the 2nd part..It's possible to open an already created assembly with more than 2 parts, turn it arround, zoom or whatever, no problems, till i want to add a new part, then -> Creo hangs up.It reloads my video card driver, but in the Creo Window "place" is shows up "no Responding".All works fine till now, exept this part.So, what can i do?Rgds.System: Win7 x64Video Card: Radeon HD4290
