Email.apk

Hi,

Yesterday I bought myself the HTC Desire, great phone.
Problem that I had was setting up my e-mail with IMAP configuration.
Google told me that the Desire e-mail application is having trouble with IMAP and that I had to install the originial email.apk from Android. So I did and I was able to set up my e-mail correctly. Only problem is that when I try to open an attachment, nothing happens. I can touch the "Open attachment", then a blank screen pops up but then the HTC just goes back to the e-mail, without opening it. Anyone have a solution for this problem?

Thanks in advance!
