Crystal Report Headers Disappear on drill down

[jayadams]

I've created a crystal report using VS2005 for an asp.net webpage using a crystalreportspartviewer. All works well...when I click on, say, row 4, column 6 it automatically hyperlinks to another page, passing query string variables to the other page where I display detail information.

My problem is that the instant I click on the R4C6 (or any other cell in the report for that matter) the row and column headers instantly disappear before I even let go of the mouse button! At first I thought it was a Theming or CSS problem, but I have disabled theming on both the partsviewer and the page as well and the problem persists. I can't help but think it is still a theming problem, because until I created the themes I did not experience this problem, though I've even gone so far as to delete the theme and .css files from my application.

Any ideas? Should I be posting this in the VB.net section instead?
