Problem with minimized chartwindows when switching workspaces

[Zapzap]

I have Win7 x64, using Aero theme, and two monitors.

Sometimes, if I minimize a chart window to tray, switch workspace, and them switch back to previous workspace, the previously minimized window shows up as a white empty window. If I click on the minimize button of the empty window, it goes down and comes back again, with the correct chart on it.
During this only the linked color button (if the chart is not unlinked), shows in the taskbar's aero preview window.

I don't know if it's a Windows OS fault, or something with workspace window restoration.

Hello Zapzap,

Thank you for your post.

I have tested this on my end and this is expected behavior within NinjaTrader 7. The chart will not populate bars within the aero window once minimized until it has been maximized once again.

Please let me know if I may be of further assistance.
