Forms45 Designer/Win95: Slow Canvas Redraw
Date: 1997/01/07

After opening a form in the Win95 Forms45 Designer tool (Forms [32 Bit] Version 4.5.7.0.10 (Production)), we encounter a problem trying to view the form canvases. The Forms45 Designer tool will partially draw a canvas object before it either locks (Task mgr -> "Not Responding" message) or takes several minutes to complete the display of the form. Once drawn, if the user clicks on one of the canvas objects, the Windows redraw event is fired and the whole waiting process repeats again. The redraw problem does not manifest itself on all canvases of a form, nor does it seem 100% consistent with regards to which objects on a canvas are slow to redraw.
Also, the problem is not occurring on all Win95 developer machines, but a comparison of machines has yet to reveal an explanation. Furthermore, it does not seem to be related to whether a connection to the database exists,or to any (obvious) configuration setting of the Forms45 tool itself. The development machines are robust: P133 or better, 32M RAM, lots of disk space, et cetera.
Any insights?
