Not sure which is left monitor, etc. For me, M11 on the secondary (larger) monitor, the floating toolbars wind up pinned to the intra-monitor boundary. However, you can successfully put the toolbars into the program toolbar, which works for 5 of the 9 toolbars.
Of the 4 that don't do this, only the programming and symbolic are really critical, but it seems to me that I can still get to all the choices.
TTFN,
