CRVS2010 BETA 2 toolbar buttons disabled

I have installed CRVS2010 BETA 2.

I have button and checkBox in window, where is crystalReportViewer.

When I click on this button or chceckBox, crystalReportViewer toolbar buttons disabled.

I had this problem also in CRVS2010 BETA 1. I hoped that CRVS2010 BETA 2 will solve my problem, but it didn't.

Please tell me how to get these buttons (and toolbar) to enable after clicking on other buttons.

Thanks

Ivana
