program is very slow

I am using version 6.33Win on a win7 PC and when I open and close pdf files it is very slow. It says “reading page ###” or “recording fonts” and often says ‘program not responding’. Any ideas?

Please try updating to 6.35 (the latest version).
If the problem persists after this, please email the PDF to support@iceni.com and we will investigate further.
If the problem occurs for all PDFs it may be related to the number of fonts installed on your system. Do you have a lot of system fonts?

I haven’t added any fonts to the system - just did a regular install. Would it matter if it was running on Virtualbox on a Kubuntu machine? BTW, I upgraded to 6.35 and it seems to make no difference. It doesn’t seem to matter what pdf I open.

I suspect the problem may be related to the environment in which it’s running. Which virtualbox are you using?

I’m using VirtualBox v 4.3.10_ubuntu r93012

Thanks. I’ll download that and give it a try.
