Paint areas outside the page with the window -background colour or light grey. Save and restore window size using -registry. Add "Paste" to system menu of text window. Make error message box -a child of text window to avoid it appearing behind the text window. To -allow user to read the error message, the text window is not automatically -destroyed in the event of an error. The user must close text window using -close button or system menu.

Change +gp_stdin.c to use fread/fwrite to be more portable. Flush redirected stdout +correctly. Added casts to fix compiler warnings in dxmain.c. Corrected +header dependencies.
