I am now messing with Dreamweaver CS3, wanted to edit some file and once I select some source code it crashes! Tried 10 times, then I googled for the error code and look what I found: http://kb.adobe.com/selfservice/viewContent.do?externalId=kb402776&sliceId=2 ^ I did exactly as it says in KB article and now everything is fine If anyone is going to face the same problem, the error code is: c0000005
