Priming experiments - transparent pictures

Aug 3, 2013 at 2:52 PM
I'm trying to use OGAMA for priming experiments.
I use Desktop Slide elements followed by Picture Slides presented for some ms.
The Problem is that the picture slides completly refresh the screen and therefore the priming becomes very annoying.
I have no idea for a workaround. I'm thankful for every suggestion.

Hi Ewald,

did I understand correctly? You would like to display text over desktop, having a transparent background during instruction?
Real transparency is very tricky in win forms, especially when using such a sophisticated window layout ogama uses for pre-preparation of stimulus.
I tried some ideas but found no quick solution... sorry.
A workaround would be a background picture with the desktop ... for the instruction slide, that useless with changing desktop I know.
