Error message comes up, indicating it's missing the library and that the app may need to be reinstalled to function correctly.

This fails on all internal and external browsers. It seems to show the error dialog every time it would've gone to show debugger text (although I'm not trying to run it in debugger). In other words it seems to show as many times as the source code would've shown up if debugger was used. Hope this helps.

As it is - it's impossible to test anything from the IDE due to a ton of these requesters all being dialog pop-ups forcing clicking on OK just to close that instance.

Any help would be appreciated, since as is - PhpEd is pretty much unusable.

Thanks.

this is due to the pgsql extention. you're getting this if you don't have pgsql installed on your system.
workaround: disable the loading of the pgsql extension if you dont need it.
fix: copy LIBPQ.dll into the php5 directory (or %windir%/system).

This has never been an issue before (well, before 5236). I'm not using Postgres... makes no sense.

this is an issue with the pgsql extension shipped with php 5.2.6

that's correct.
To workaround the problem please install php from the link posted there

Thank you!!!
