I have installed PDFCreator 1.3.2, with PDFArchitect 0.5.2.450.
When I open large PDFs (>6Mb) of scanned sheets, only the first 8 sheets display anything in the left panel.
Works well with small PDFs.
Memory usage shoots up from 680Kb to 1.8Gb and everything slows down.
If PDFArchitect keeps running, I can manipulate the pages, but cannot see their content.
Probably a memory issue.
I'm running WinXP Pro SP3 with 2Gb RAM.
