A few questions with probably short answers(?). - What's the reason for getting an Alloc-error when creating a pixmap? Is there an overall limit to the size (say 2048)? Where is the pixmap stored at the server side: is it VAX memory or is it "screen memory" which happens to be beside the video screen? - What is the max. size of a userdefined cursor (the size of the shape and mask bitmaps)? - Is there an LSE package available for X, Xt, and Dwt-routines? If so, for what languages? If not, any plans? Thanks for any help, Hans.

That means there's one question left. > - Is there an LSE package available for X, Xt, and Dwt-routines? If so, for > what languages? If not, any plans? Any new info yet? Thanks for any help, Hans. | |||||
