We have Infragistics2.Win.UltraWinChart.v8.3

When our (Windows Forms) application generates graphs, tooltips in the graphs are properly shown when users hover mouse around graph elements.

But when the application is loaded via Citrix presentation server, tooltips from the same graphs will not be shown. these graphs are normally created inside UltraTabControl inside UserControl inside Win Form object.

Two interesting issues we noticed are:

1. if we minimize and restore OR resize the main window (citrix) , tooltips suddenly show up correctly.

If another graph is freshly generated, tooltips inside that will not work again. minimize and restore, and tooltips will work for that graph too.

2. Even when we load the application via Citrix, if we put our graphs inside floating window object (not inside ultratab in main window) then tooltips work properly.

Since the bug happens only when on Citrix, it's hard to debug or figure out what's causing it to happen.

What can be the solution to this kind of problem?

Thank you.
