#204 win7 taskbar: progress of batch tonemapping still displayed after closing dialog

[Gust Fried Wert Hegel]

The progress of the batch tonemapping dialog is displayed in the windows 7 taskbar.
When closing the dialog (after it finished - and displayed 100%) I expect the progress to be cleared again in the taskbar. But the progress bar stays visible in the taskbar.

Environment: Windows 7 x64, Luminance HDR 2.4.0
See attached screenshots before and after closing the batch tonemapping dialog
