I am using visual basic 6 with crystal reports 11 (XI) to generate some reports.
The method I use is to create an rpt template report file and passing it on a CrystalViewer control. I tested my .exe file and everything seemed to run correctly.
However, some days ago Iíve noticed that in some PCs the preview of my reports are just empty pages. To make thinks complicated this happened randomly and I cannot reproduce the case in my development environment. The report is exported to pdf or printed perfectly, only the preview has problem.

Also, I can browse through these blank report pages using the default report toolbar , there are no data appeared on them. The fields are able to be selected (highlighted ) when someone drags the mouse cursor on blank page like this, but still no data appear.

Has anyone else faced this problem? Can anyone give me any advice ?
