Hi brabe,
Based on your description, it seems that it is not the VS IDE issue, just to make this issue clearly, whether this issue is related to the SSRS or the report control?
If it is related to the SSRS like these threads
here and
here, my suggestion is that you could post this issue to the SSRS forum for dedicated support.
http://social.msdn.microsoft.com/Forums/en-US/home?forum=sqlreportingservices
But if it is the Report control issue, you could get better response from this forum:
http://social.msdn.microsoft.com/Forums/en-US/home?forum=vsreportcontrols
If I have misunderstood this issue, please feel free to let me know, please also provide detailed message about this issue, I will help you find the correct forum:)
