in PADS9.3.1 i have created a hierarchical schematic with one top view and several block symbols containing schematics underneath.
When i create a block symbol from the schematic it transfers the pins to the top level overview.
But whenever i try to edit the block symbol to manually arrange the pins, the symbol deitor sometimes opens just in a blanc screen.
When it does open the symbol, i cannot move the pins, because of an error message poping up: "empty selection no items passed to the command"
Please see attachments.
Any idea is very much appreciated.
