Hi,

One of our client reports a issue where the data in the UltraGrid doesn't show unless the user mouse hover over the grid, or scroll the grid.

We have UltraGrid on the tab that displays patients data. The tab also has an option panel and other controls. When the client switch between different patients, the data on the options panel and in the grid is refreshed to show the current patient data. Randomly and intermittently when they switch to a patient, data will be missing from the grid (but the options panel and other controls display correctly). Then if the user hover mouse over the grid and moves the mouse, the data appears, as if the mouse movement cause the UI to render.

Client accesses the application through Citrix, they said the issue only happened through citrix. We haven't been able to reproduce the issue in house yet.

I've attached screenshot.

The UltraGrid Version=13.1.20131.2060

Client didn't have this issue with older version of the application which uses much older version of the UltraGrid.

Please let me know if you've seen this issue before and if there is any resolution.

Thanks,
Ying
