When opening a PDF in IE it will display oddly, and then say Power PDF has stopped working. This issue happens intermittently.
Check display settings, if one make sure display settings do not exceed 100% on either of the displays
More info: According to ZEON this is due to a limitation of the basic framework of PPDF 2.1, we can't change the window size between screens.
It is fixed in PPDF 3.0. PPDF 3.0 18252.1100
