Hello,
I've got a very basic report that I am trying to load in my WinForms app (targeting .NET Framework 4.0, x86) and the Crystal Reports Viewer is freezing on me while displaying the "Please wait while the document is processing" spin-wheel message.
Note that the wheel stops spinning and it does in fact seem to "freeze". I am bringing up the form that displays the viewer using ShowDialog() from my calling object and after the form freezes I am able to go back and use the calling form.
I've tried removing and re-adding the Crystal DLLs, various variations of the code to show the viewer and the form, loading the report statically from the VS Form Designer, nothing has worked.
Also of note is that the Report loads fine when I load the rpt file in the Report Viewer object from the Visual Studio form designer, but it will still freeze when I run my app.
I've also tried loading different reports. The test report I'm using now consists of nothing but a "Test Report" label in the Page Header section (no data-set or database access).
Edit: I'm using CR For VS 2010 (version 13.0.18), which seems to be the latest.
