I just noticed something odd with the crystalReportViewer control.
I added a crystalReportViewer to a tabPage in a tabControl on my form and all was good.
Then at some point I locked all the controls on the form by right clicking the form and selecting "Lock Controls". The next time I ran my app and wanted to preview a report I noticed that the "toolbar" buttons on the crystalReportViewer control were gone. It took me several minutes to figure out that locking the controls on the form caused this.
Did I stumble over a bug?
Any attempt to explain this would be appreciated.

Thanks,
Einar

PS. I have not tried to put the crystalReportViewer control directly on the form and then lock the controls on the form to see if I can observe similar behaviour.
