Man this is a nasty bug!!!! The only work around that I could come up with was to split up my listbox items into cursors and setup buttons for the user to select the group (ie. A-D,E-H,I-K, etc.). The user then clicks on a button that fills the list with all items starting with that letter. It works but I hate it! And I still get memory errors from time to time even though my biggest list is only a little over 400 items! I'm running a Pentium Pro 200 with Windows NT 4.0 so I'm wondering if the faster the computer the lower the number of items that will cause this memory error. Geez.
