Issue #340 resolved
- Take a project saved in a database with ~100 waypoints and open it in the workspace.
- Select all waypoints in the workspace.
- Click Change icon .. in the context menu.
- A progress window with the title "Please wait..." appears which can be seen for quite a while and which shows a "nervous" behavior (proper content of the window can't be seen, too many refreshs of the window or window opened and closed again and again? Map background can be temporarily seen through the progress window. Progress bar of the window more or less not visible.).
This doesn't happen, if the waypoints are selected from a project saved in a GPX file. With the same number of waypoints the icons are changed more or less immediately and without having/seeing a progress window.
