I encounter a serious problem on a TCL/TK application. When I click on "Home", the cursor goes to the beginning of the paragraph and not to the beginning of the line. The same with the "End" key. It goes to the end of the paragraph and not to the end of the line. 

Finally, to top it all off, when I use the up or the down arrows, they don't move the cursor to the line above or below; they move it to the line where the paragraph starts or ends. 

What causes this serious and very painful problem? What do I do to fix it? Thanks!

[NEM]: Wait for Tk 8.5 (or use an alpha release): TIP 155[http://www.tcl.tk/cgi-bin/tct/tip/155.html] provides the functionality you need, AIUI. (BTW, it's not generally a good idea to use this wiki for questions, and less so to create a new page for a single question. news:comp.lang.tcl is a better place for such queries.)
