Groups and Layers

Now the last release of DSP works fine with layers within groups, also save and open dspx file works ok.
But after removing a group or a layer from legend and then click to one of existing item in the legend I receive below message.

This happens only on group with layers after I reload dspx file. When I create one group with layers and then try to remove it this works ok.

************** Exception Text **************
System.NullReferenceException: Object reference not set to an instance of an object.

Also when open and remove the same TIF image (size 77MB) the third time program reports Out of memory.


Thanks for any help on this, Vojko

Found the problem. Instead to insert the code for openning map dspx file into MainForm_Load event it must be in the MainForm_Activated event.
