Hi Dave,
Love this script too. Had a small change to the script you might want to add. It's just related to the positioning of the Gui.
Right after you read in the x and y positions from the ini you may want to add the following lines.
<font class="small">Code:</font><hr /><pre>
IniRead, gx, %inifile%, Defaults, gx
IniRead, gy, %inifile%, Defaults, gy
If (gx <= 0) Or (gx >= A_ScreenWidth )
LastGuiX = Center
If (gy <= 0) Or (gy >= A_ScreenWidth )
LastGuiY = Center
</pre><hr />
What this does is ensures that the Gui will be visible. I had problems previously with your script if I switched from using dual monitors to a single monitor, or if I changed the screen resolution. The script would load but the Gui would be "off-screen".
BTW, if you'd rather I PM you with this stuff or do something like this over at overcards.com, let me know.
I think you're doing some really interesting stuff right now, keep up the good work.
