[CentOS] How to open files (by double clicking) in an existing gphpedit window?

Hi,

I have been using gPHPedit for a few weeks now, and I am most pleased with it.

Needlessly to say, I have associated the .php extension with gPHPedit, such that PHP files open in gPHPedit upon double clicking them from the file browser.

Alright, all swell, however, each file opens in a new gPHPedit instantiation, whereas I'd like the very first one to open gPHPedit and open the file, and all subsequent ones to just be opened in a new tab in the existing gPHPedit thread (just like Ultraedit does under W*nd*ws).

Does anyone know how to achieve this?

Cheers, Olafo
