I have a wacky case where the Open URL command does not open the correct URL. This behavior occurs when calling Open URL from a script, as well as a button assigned to open a different address.

Let's say I want to go to http://website.com/lets/go/here/

When triggering the Open URL command with either the script or the button sends me to http://website.com//lets/go/here

Notice the double slash after .com -- that's the problem. If you remove the extra slash from the browser's address bar, the address is correct.

Further, this only occurs on one machine, a Windows XP box running FileMaker Pro 7. The behavior occurs in Firefox 1.5 -- I don't have the necessary rights to set IE6 as the default browser to see if it happens with IE.

However, other systems, both Mac and Windows, IE and Firefox, don't have this problem. Unfortunately, the machine with the problem is the machine that needs this to work.

Short of calling my IT department and having them upgrade to Firefox 2 to see if that helps, can anyone provide some suggestions for me to try?

See if this helps.

Ah, so it's a known bug, great.

For anyone else, the suggested fix on the other page didn't work, because then the URL in Firefox contained all %2f instead of any slashes. However, the following did solve my problem:

Substitute ( URL ;

[ "http://" ; "" ] ;

[ "//" ; "/" ]

)

It does work for me (Firefox 1.5 on OS X).

BTW, your second substitution doesn't really do anything: after removing the leading "http://" there are no more double slashes in the URL (or at least there shouldn't be).
