Whenever we use swimlanes, including nodes in a drawing, yEd gets slower and slower after a while. The lag between action and effect renders the usage very difficult. As a remedy we have to restart yEd.
I checked the memory allocation using the Windows Task Manager, but that looks insignificant.
Other drawings we use, even with hundreds of nodes, edges and labels aren't showing this effect on the same computers (all Windows 7 64bit).
We experienced this with version 3.13, 3.12 and 3.11 (each with included JRE version)
Thanks for ideas regarding this matter.
