Ahhhhhh, I knew I have seen this issue before. And I have already fixed it. This was a problem in the DOM. Its in the 1.1.0 release but has been fixed in the SVN. If you check out from there you will get that fix, plus much much more.
When Mike Weiblen packaged up the project to hand over to the OSG community he included prebuilt libs from the SVN, not the 1.1.0 release package. I don't know if they are still being used but if you download and build the DOM1.1.0 release you will have this problem. If you use the prebuilt libs (or get from svn) you wont. -Andy P.S. I am planning on making another release package of the DOM sometime in the very near future. Andreas Ekstrand wrote: > Hi Roger, > > Thanks for your efforts!
