IAR 8.20.2 crashes on Win8 when stopping debug

Finally, found solution about IAR8.20.2 running on Windows 8 will cause crash when stopping debug. This issue troubles me several months.

Still have problem on register view, even if I delete some in .sfr.
I decided to change to IAR 8.30.
But it needs to modify the below file.

• EW24413: Linker configuration files (with the filename extension .xcl) from version 8.20 or older contain:
  -Z(DATA)VREG+_NR_OF_VIRTUAL_REGISTERS=08-7F.
  In the 8.30.1 release this internal _NR_OF_VIRTUAL_REGISTERS symbol was deprecated. In the new version of these files, this changed to:
  -Z(DATA)VREG=08-7F.
  This change is now also applied to the Texas Instruments (Chipcon) linker configuration files.

Open $PROJ_DIR$\..\..\common\cc2540\ti_51ew_cc2540b.xcl  

Change -Z(DATA)VREG+_NR_OF_VIRTUAL_REGISTERS=08-7F to -Z(DATA)VREG=08-7F
