loss of pin properties in full featured 2c35

[Altera_Forum]

Working with the full featured design for 2c35 I bump into the loss of the pin properties in the bank from >clk_to_sdram[0]......ddr_we_n[]<. Suddenly the pins are no longer connected to the location assigned before. An reimport of the pin assignment fails. Even if I save the design this happens. 

 Does anyone know the reason for this behaviour of quartus 5.0?     Thanks in advance.  andy

Hi Andy, 

 if you are doing what I am thinking... when you (re)assign pins, you should first close the project and quartus and restart it before you can use it. First save of course before closing it http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/wink.gif . but it&#39;s a bug in Quartus II.  good luck,  Danny
