SYMPTOMS
If a program repeatedly calls the LoadAccelerators function for the same accelerator table, the 64 kilobyte (KB) user handles may be exhausted, and the computer may stop responding (hang).



CAUSE
The LoadAccelerators function should only load the accelerator table if it has not yet been loaded into memory, but it loads the accelerator table for each call (even for the same accelerator table) instead.
