Andrew Sykes commented on OFBIZ-567:
------------------------------------
I have just double checked the XFCE/FC3 combination mentioned by Jacques above,
there is no problem for me with this combination, however Gnome/FC3 displays
the blocking window on top, but if you hide it, you are stuck!
My XFCE version is 4.2, the version Jacques was referring to above (in
combination with Ubuntu was 4.4).
Perhaps this answers the problem of why Andy couldn't remember which WM worked,
i.e. perhaps you need an older XFCE for POS to work.
This is really beginning to sound like a WM issue as Andy suggests.
Perhaps this could be resolved by simply redrawing the main window to show
alert messages rather that using a modal window?

> Hi,
> I am experiencing a big issue using OFBiz Point-Of-Sale application over
> Linux (Debian Etch) with Java JDK 1.5.0.x
> The problem is that the POS main screen behaves like a modal blocking window
> in Linux. Once the main screen is displayed, you cannot
> switch to another window of the system with Alt+Tab. What is worst, when the
> application tries to display an "Alert message" (like
> for example "Product Not Found" when you press SKU) the alert is actually
> presented behind the main screen, instead of on top of it.
> So, you cannot accept the message and you can neither do anything with the
> main screen: the application is blocked. Then I have to
> log in with a different TTY and kill the java process.
> This behaviour is not reproduced over Windows XP with the same Java JDK: you
> can swith to other application with Alt+Tab and alert
> messages are properly displayed in top.
> I just wanted to ask if anyone has tried POS over Linux and experienced such
> a problem. I'm a newbie to OFBiz and maybe I am doing
> something wrong. Otherwise, this is a big issue that has to be put in Jira.
> BTW, should I put the issue in Jira myself or is it
> restricted to developers ?

> 1. Alt+Tab problem
> I just tried on updated Ubuntu 6.06 LTS (Dapper Drake) using last svn (rev.
> 490054) and Sun JDK 1.4.2_08 without any problems at all
> (BTW I never saw this problem before but must acknowledge that I'm worling
> more on XP). Did you try to use your mouse to switch to
> another task ? Is it only alt+tab that is not working ? Something strange
> though : Alt+Tab shows 2 windows for the POS : one
> labelled "OFBiz POS" corresponding to inner POS window and another one not
> labelled at all and corresponding to a frame (you see the
> frame only before loging) around what I suppose is the main window (the
> inner one). This last window may also corresponds to the
> splash screen not closed(?) because when lauching the POS I see one window
> without name related to the POS.
> 2. When (for instance) the "Product not found" dialog box is (normally) shown.
> In this case I can see also 2 POS related tasks with alt+tab and may access
> to others (non OFBiz POS) tasks without any problems.
> But YES I'm caught in POS and can't get back to it because the "Product not
> found" dialog box is no more accessible. Now if you try
> to do same thing with the modal box that appears when you use "Save Sale" you
> get the same behaviour. I tested this because these 2
> windows are not build in the same way. "Save Sale" is a pure XUI window.
> BTW I confirm that they are no problems on Windows.
