Cool VL Viewer forum

When you open a file dialog to save or load something, the viewer is completely deadlocked: it will not do anything while the file dialog is open. This normally would not be much of a problem. However, networking is also deadlocked while the file dialog is open. If you take too long in the file dialog (having trouble locating a file, for instance), then the connection times out, and you get booted when you close the file dialog.

Would it be possible to put in some kind of "keep alive" workaround to prevent this?

Please note that this issue is not specific to the Cool VL Viewer but applies to all viewers (official or not)... You should therefore open a new issue on the JIRA (if it doesn't already exist).
This "deadlock" is the result of the GTK file picker monopolizing the glib event loop. A solution would be to thread the call to the file picker, if at all possible (I have bad, old memories with GTK+ threads, though it was GTK+ v1 back then)...
