I have installed ProgeCAD2011 which is based upon IntelliCAD 6.6. When I add text with the Mtext command, the whole program freezes and the CPU usage goes up to 100%. I have installed Riched30 together with mls31 (MS Line Services). This bug is already mentioned at https://bugs.winehq.org/show_bug.cgi?id=11751 "Intellicad 6.4 becomes unresponsive when adding text (mtext command in icad console)". I run ProgeCAD 2011 under Linux Mint 17.2 Xfce with the 3.13.0-65 kernel. The Wine version has been set to 1.62 in PlayOnLinux.
