JSI Tip 1000. Does Drag-and-Drop to/from a floppy freeze your system?

This could be a problem with your high performance video card and BIOS. If it is, you may be able to resolve the problem by using Regedt32 to navigate to

KEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers

Add Key name DisableUSWC and leave the Class empty.
