[josm-dev] R: R: R: R: R: FW: [OSM-newbies] JOSM problems - is it just me?

[Fabrizio Carrai]

I enclose the message I sent with the solution that I found.
As discussed in the JOSM trac, the problem is in the Java machine.
I'm not an expert, but it seems that it can be done very few at the app
layer.

Ciao

It looks like I found the solution!!!
It seems to "happen with machines with low video ram". I've an NVidia
Geoforce 6150 (shared memory 512MB): no idea if it falls in such category,
but now it works!

As in [1] the solution is to start JOSM including the Java option
"sun.java2d.d3d=false":

C:\WINDOWS\system32\javaw.exe  -Dsun.java2d.d3d=false  -Xmx800M -jar
C:\Programmi\Josm\josm-latest.jar

I'm now working since several hours with JOSM doing several changes and
uploads: no crashes till now! Before it was happening after very short
editing sessions.

Continuing testing!

Ciao!
