NPE when clicking on the map

[Zverikk]

I use a pen tablet. Sometimes, very rarely, I get this exception when I click on the map. Also, after that it zooms to the limit, so I have to zoom out for a bit.

Sorry, I was mistaken. Zoom level was not changed, just the whole screen turned grey. When I closed error message and pressed "zoom out", everything was back as it was.

First click after starting JOSM or also later?

Did you have it also in versions <= 3701?

[Zverikk]

Just got this exception. It occured when I tried to drag the map. Not right after starting, and not the first right-click.
This exception started appearing about month ago. Once I've received it using mouse.

[bastiK]

what do you mean? Pen tablet with mouse?

[Zverikk]

Pen tablet or mouse, with any device sometimes this exception occurs. Is it possible to include additional information in that exception, so I can put it here next time?
