I am using PhpEd 5.0.1 build 5028. I am not able to make launch box work. I read the manual. It's supposed to automatically add what I ran last to the box (and optionally give a confirmation dialog box). However, after I click run either through the toolbar or go to run->run through menu, nothing is added to the launch box.

I checked Tools->Settings->IDE->IDE settings, the "Run History" is set to 5.

In the launch box itself, I can click on the icon that looks like a finger on top of a rectangle, and reach the preference dialog for the launch box. I found that:
Launch box settings:
Keep history = 10
Remember each run = checked
Confirmation dialog = checked
However, if I click "projects" on the left hand side of the preference dialog, nothing shows up on the right hand side.

How can I fix the launch box?

I was getting ready to paste the exact same thing. I cant get the Launch Box to work at all. I'm on the same version (5 build 5028 - I've downloaded 5029, just not installed it yet). My settings are identical to stanza2100 except that I actually have pages listed in the projects area. However, nothing is listed in the Launch Box, no confirmation page ever shows up when I run the pages, etc. I've even tried adding POST/GET data in the settings for a page, but that information is not being used when I run the page.

Not sure what else to try...

the problem was introduced in 5028 and it is already fixed in 5029
