Seem to have a problem when trying to open certain pdf files. The files can be opened without any issue on a PC but get the 'unsupported security handler' error when trying to open on the desire (froyo updated). Not actually tried these files prior to the froyo update so unsure whether this is a bug? Downloaded Adobe Reader as an alternative viewer, this time it opens but the pages are blank... Think it's something about the pdfs as they were written in Acrobat Distiller 7.0.5 for mac... Any ideas would be much appreciated.. thanks.
