Leak in TomTom Home 6

I have a TomTom Go 740, and the latest (2.6.1.1549, non Beta) Home has a GDI handle leak in the "operate my go" mode. If I leave it, then after a while other apps stop being able to display properly. Process Explorer shows Home eating handles at a rate of about 20 per second, going from 700-ish to over 2000 before I see effects in other apps.

Can you say how you are seeing this?
I'm no expert on Process Explorer (I'm assuming you mean the Task Manager replacement from www.sysinternals.com) but this is what I'm doing:

Run Process Explorer
Set it to "show lower pane"
Set Lower pane view to "Handles"
Run Home
Run the Emulator

Select the "TomTomHOMERuntime.exe" line in Process Explorer
This produces an awful lot of entries in the lower pane, and the CPU load sits around 50-60%, but the Handles don't seem to keep going up.

This was with the same Home version as you, but a 940 connected.

I'm looking at the GDI Handles column in the upper display. The number of handles is fine until you start the "Operate my Go" mode, at which point it climbs steadily.

Maybe I need a newer version of Process Explorer (mine's v11.13)
I can't seem to see any way to get GDI Handles in the top pane.

Edit: Downloading v11.33 now...

This is from the Help file, Andy...........

The Process Explorer display consists of two sub-windows. The top always shows a list of the currently active processes, including the names of their owning accounts, whereas the information displayed in the bottom window, which you can close, depends on the mode that Process Explorer is in: if it is in handle mode you will see the handles that the process selected in the top window has opened; if Process Explorer is in DLL mode you will see the DLLs and memory-mapped files that the process has loaded.

Does that explain things at all?

Think it is this.........in the application, View/Select Columns/Process Performance/ Check 'handle count'

Got it now (lots of different places to switch columns on and off!)

I've ticked "Handle count" in the "Process Performance" tab and also "GDI Objects" in the "Process Memory" tab

... and sure enough, they are both increasing steadily.

Wonder if this might explain the problems I and others have seen where the app seems to freeze in 'Operate my Go'.

This seems to happen after a short while of using Operate my Go.

There is talk that a new version of Home will be released tomorrow (well, April 8). If so, maybe there is a fix.

See, I've a lot to learn.... I know about door handles, but window handles were called "latches" in my day. Confused

Checking today tells me a "Critical update" is now available for Home.

Which seems to have cured the freezing of the on-screen emulator if it is left idle for a few minutes.

But the Handle count and GDI Objects are still counting ever-upwards...
