weird pws + activeperl problem

[MateIn1]

I'm having a strange problem w/ Active Perl. I'm using it with Microsoft Personal Web Server on Window Me. It's been fine for about a year but I just reinstalled everything and can't get the browser to run scripts. I added the .pl and .cgi extensions to the Script Map section of the registry but no luck (They were mapped to c:\perl\bin\perl.exe %s). Here's the weird part. I made up some extensions (.xpl and .zzh) and put them in the registry also (under Script Map). The scripts ran w/ these extensions but not with .pl or .cgi. To make things even stranger, I removed .xpl and .zzh from the registry completely, but the scripts still run with those extensions. I can't find the extensions anywhere else in the registry or in any files. What I really need is to get .pl and .cgi files to run in the browser. By the error messages (Error 500) I can see that .pl and .cgi ARE recognized as scripts, but they just don't ru! n. Does anyone know why those extensions don't work and/or why the other two extensions worked and why they continue to work after being removed from the registry? Is there a hidden system file somewhere that is holding that info? Thanks in advance.
