I m deleting some png files in previews and crash problem solved.
Hi there ^^, I already fixed the Vista crash issue
I'm waiting for official verification from Barry, but the issue wasn't related with the PNGs, it was with a portion of code that wasn't properly implemented for the sensibility of Window Vista xD. It seems vista handles Boolean variables in a very strict way when comparing or checking their values.
Oh btw, PNGs have issues sometimes when they have a very rare structure, FBA have that issue long ago but Its not really FBA code problem, its 'libpng' library issue it seems. I was able to correct issues with the problematic PNGs with a rare structure opening them in PhotoShop and saving them in a new file again using the mentioned application for that purpose, the PNG should then work fine when opening in FBA ^^.
SeeYaa!
