Why is GnuRadio companion not allowing me to add blocks? -

i have installed gnu radio , grc 3.7.2.2 on 32bit xp machine next instructions from ettus. starts without messages, can open existing flowgraph, delete blocks, edit block properties, cannot add together new blocks. double click on block has no effect. nor dragging it, right clicking or other gesture think of. can think of problem might causing this?

update: turns out homecoming works, not double-click

it sounds having issues installed graphics libraries. did install whole list of dependencies in instructions?

you should e-mail gnu radio mailing list what's going on: https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
