SYMPTOMS
Power Launcher and hDC work only with 16-bit applications.



CAUSE
These applications install global hooks. Because 16-bit applications cannot hook 32-bit applications, the hooks are global only for the 16-bit Windows on Windows (WOW) virtual DOS machine (VDM).

As a result, these two applications hook all 16-bit applications and then exit when there are no 16-bit applications left running.
