depends, as far as i know theres not a single software out there thats totally bugfree. that of course doesnt mean it has stability issues, but i woudnt claim that any application that i know of is perfect. Other then that i very much doubt that something happens if you report a bug, reporting bugs is something every developer i know of encourages, but spamming about the same bugs over and over or talking thrash is another thing. so to answer babas questions, i dont know if his problems are fixed or not, if he has had stability issues with every single vue version hes ever tried he might have the same issues this time around aswell, ive had zero problems with vue4 and pro on my computers as far as stability goes and with a few exceptions rarely been bugged(open gl for one) Vue5 has worked realy nice for me including open gl, exception being one computer rig, and as far as i know most others that has tried it has had a much better experience then with vue4, but ive seen atleast one more vue5 user (cnevian) having the same issues as me on one of his computers while it works perfectly on another, so some issues still exist, but they seem to be quite rare. software,driver,hardware related? no idea.
