Well just tried getting to 4.06 on different machines. Stand alone Win98, SE, installed 4.00, updated direct to 4.06, still having same error writing file on alpha planes, even to the vue/picture folder, nothing else on this pc except window/photoshop and vue, 40GB drive. Non network Win2000 pro, installed 4.00, updated to 4.06 direct, same issues, multi drive machines, other software, space no problems, all microsoft patches applied by network, no other issues, can not save alpha's. Reinstalled 4.0 again cleanly, updated each upgrade, got to 4.06, same issue this on both machines, each had a fresh download of the 4.06 upgrade, however noticed that one download was 9.147MB, the other was 9.1469mb, on T1 lines, ??, possible download issues, tried again and got 9.147 twice, same alpha save problem. Sorry folks, but am gonna stay at 4.05, does all that I need with the only occassional "vue not responding issue" when rednering to screen, can manage with that. Also tried using just the render options directly without right-mouse on the picure-icon, same issue. Gary.
