Same mobile workstation.
GDI set to 10 000 but not useful.
10.000 is the default value for GDI objects - and still to low.
I set it to 65.000 (near the max. value) and i'll be fine since then.
I verified this setting with opening around 50 files. With the GDI setting to 10.000 SWX will crash after opening around 16 files. When changed to 65.000 it will open all files flawlessly...
So please give it a try!
