problem occurs after Create get 'x'

[karaltan]

i think there is a mistake with variable blocks.
issue: i create a variable block, for example x. after that, i click right button and click "Create 'get x' " and there is a block for me to get its value. this is ok. but after that, when i goto toolbox, i can not drag-and-drop any blocks from toolbox into workspace!!! before "Create 'get x' " everything is ok. but if i make "Create 'get x' " block, no other blocks in the toolbox can be draggable.
