open dspx with layer label is slow

I added shp layer and set labels for that layer and saved as dspx file with your latest DemoMap from DotSpatial ver 1.3. When reopening it takes this dspx file about 10 secs to open. After that when I try to add new layer the program stops working. 

This also happens with MW6, only MW4 works OK!

>>> 22.20.

The problem arrise when dspx file is in different folder as shp files!  But reopening the created dspx file with shp file cca 1MB with one label setup it takes 20 secs !!!! This is too much. And all other manipulations with program takes too much time. If now I try to open small 50kb shp it takes 25 secs!

>>> 20.10.

The exact file path for my shp file is 'C:\Mapgis\SHP\CEV_PLIN.dbf'  but as I can see from the message report bellow report shows 'C:\Mapgis\SHP\SHP\CEV_PLIN.dbf'   >>> there must be only one  C:\Mapgis\SHP not doubled 'C:\Mapgis\SHP\SHP\  !!!???

What is happened here! Is there any help on this?


>> 5.11.   still need help on this !
