PHP as apache module side-effect

Hi All: I don't have a dedicated server for my office intranet (15 computers), so the strongest workstation doubles as web server (I know, I know, not the best choice :( ). After installing PHP as an apache module a strange side-effect appeared: I usually start all applications (ie. Word, Excel, whatever) using hot-keys, but now every time I press a hot-key the computer suffers a short (about 5 sec.) "lockup", and then starts the invoked application. After some testing, I found the following: -It happens every time. -Only with PHP as module, not as CGI. -Tried with Win95 and Win98, and both suffer the same problem. -Happened with PHP 4.0.2, 4.0.3 dev and 4.0.3 (didn't try previous versions). -Doesn't seem to have any other negative side-effect. My Apache is 1.3.12. Anybody else having this problem? Would a bug report be justified? Any suggestion on how to fix this? Thanks, Gonzalo.
