Quote - the trouble is back....

please somebody help me, it's impossible to use....

Well I'm no expert but I am running P8 sr3 with no problems on Win7. In fact the IDL rendering seems faster after the sr and the library is a bit better as well.

Give us more info and maybe I or someone else here will be able to help. To start with what operating system are you using? The guess from your screen name would be XP but assumptions won't help. You might be on a Mac or Linux. Is it only one dynamic cloth or all that you have tried using? You get the idea. The more info we have the better our chances of helping you out.
