Next and Previous desktop keystrokes only go one desktop without releasing Alt and re-pressing Alt

[GoogleCodeExporter]

What steps will reproduce the problem?
1. enable Alt-cursor to switch next, previous desktops
2. keep Alt held down, then try to do more than 1 cursor presses (left or right.
3.

What is the expected output? What do you see instead?
If alt is held down, you should be able to page through your desktops using the 
cursor key pressed any number of times.
What actually happens is that most of the time I only get to go one to the left 
or one to the right.  Occasionally I can go right then left.  But never 2 
desktops to the right or two to the left (or more.)  By releasing the Alt key 
and re-pressing the Alt key I can then move the next desktop over, but this is 
cumbersome when I want to quickly flip through my desktops.

What version of the product are you using? On what operating system?
1.6beta3

Please provide any additional information below.
This is a pretty sweet virtual desktop program, but I have been hardwired over 
the years to only use next and previous keystrokes to switch my desktops, so 
it's vital to me to be able to easily go more than one to the right or left 
since it's my main way of moving through them.  Being forced to release the Alt 
button every time feels completely unnatural.

This seems to also be the case with Alt-1, Alt-2, etc.  I need to release the 
Alt key or I can only press 1 or 2 different numbers and after that I get the 
Windows error sound for additional number presses.

could you try another keyboard?  you may be using a keyboard which doesn't 
support nkey rollover, or alternatively not sending make/break codes 
appropriately.

note: I'm just a user, and my paging key is control, so I haven't tried to 
replicate your bug other than to say it's not a problem for me with cntrl on my 
computer.

I'm running Windows 7 inside of a vmware fusion virtual machine.  All I know is 
that mdesktop is the only program that gives me this behavior.  All other 
programs (and virtual desktops) seem to work fine with holding down the 
modifier key and pressing different keys.

Perhaps mdesktop uses a method for capturing key presses that works in many 
computer situations but not all?

Came here looking for this issue. Tried installer, and compiled 1.6b3 from 
source, and in both cases noticed this issue. Ctrl-Left and Ctrl-Right work 
whilst holding down control, but if you use Alt as the modifier, you have to 
release it and press it down again for it to work. I'm on Win7 64-bit. As 
stated, it applies to both the next/prev hotkey and the desktop-chooser hotkey 
(Alt-1,Alt-2,etc).

One other data point. This morning I accessed my desktop through Remote Desktop 
Connection, using my laptop, and surprisingly the Alt-Left/Alt-Right navigation 
worked without having to release the alt key. I think it's a keyboard specific 
issue. I'll try to get more data when I'm back in front of the problematic 
keyboard.
