Missing task bar on a laptop with a "part time" external monitor

Hi All, I've got another problem after upgrading to Mageia 5/Trinity r14. When working for clients on-site, I will usually take my own laptop with me and plugin into an external monitor + keyboard while there. I have a script which automatically detects and extends the desktop to the external monitor when I log in. My task bar defaults to the external monitor when present and is shown on the laptop screen when there is no external monitor. This has been working perfectly for years. However, after my latest upgrade, the taskbar no longer displays on the laptop screen if I boot up after having previously used the external monitor, making my desktop unusable. The problem seems to be that the taskbar display is now "fixed" to whichever monitor it was last set to display on, regardless of whether that monitor is actually present or not. The external monitor output isn't actually being enabled due to a mis-detection, there is no signal output on the monitor port and the desktop has not been extended off the visible area of the laptop screen in any way. The only solution I have found so far is to plug into an external monitor, enable that monitor with an extended desktop using my script (which runs xrandr) and manually drag the taskbar back to the laptop screen. This is OK when I have a monitor available, but if I'm out and about with no monitor available, I'm a bit stuck and have to use XFCE instead. Ideally it would be nice if the prior behaviour was restored, but I'd settle for a simple script run during login which can move the taskbar back to the laptop screen every time I login, it's not a big deal to drag back to the external monitor after I login. Is there any way to achieve this? I'm thinking that either there is a command I can issue which will move the taskbar location on demand, or alternatively I could use something (eg sed with a regex?) which re-writes the underlying config setting before the task bar starts (where is the config setting?)!
