Windows 7: Thumbnail view - cursor redraw problem

[Samuel]

If I move the cursor up and down (by keys) in the thumbnail view of Windows 7 the cursor sometimes isn't shown or is shown with a "lag". (It is shown always if the thumbnail view scrolls because of the movement)

If its not shown I can minimize and restore TC to show the cursor. (I can also use the right and left arrow keys to show the cursor.)
I cant reproduce it for 100%. There is no Thumbnail-generation in progress or any other load from another task.

Sometimes I can reproduce it when I press "Windowskey+d" and switch to TC afterwards.

I have the same problem. When I move the cursor with the up or down
arrow keys I sometime (very seldom) see it move... but most of the time
nothing happens and then it just jumps to the file/folder I moved it to.
But most of the time I can't see the cursor at all and the only way to know
where it is is to press the space bar and then when it selects the file I can
see it again... but that's not fun if I'm on a directory with a lot och files : )

[Samuel]

Can you confirm that:
- its only the Thumbnail mode
- its Windows 7
- its only the vertical cursor movements
- you can make the cursor visible by pressing left or right?

BTW: the cursor never disappears here. It just stays at the last file.

Someting is wrong with the windows 7 compatibility cause the same total commander 7.5 (portable usb version) works well in windows XP and Vista but the same TC does not work properly in Windows 7 the cursor freeze when you tried to move down or up using keyboard.

I probed diferent TC versions and all had the same problem using Windows 7

Can't see anything buggy. Win7, TC 7.50. Panel with almost 2k thumbs, different window heights. Cursor always being moved correctly.

[Samuel]

Happens here with 10 Thumbs. It just needs a second line.

[MVV]

Maybe you post a screenshot?

I have tried to reproduce this problem on Windows 7 too, but failed. Maybe it happens only with a certain number of thumbs per row, or a certain thumbs size or window width?

[Samuel]

Mh tried it with a new ini and failed.

You need to switch: "Configuration > Color > Cursor color" to a custom color.

[ghisler(Author)]

I tried this both with a colored frame and an inverted cursor (full color), but the redraw was 100% correct!
- What else did you change in the new ini?
- How many columns of thumbnails are shown?

[Samuel]

- What else did you change in the new ini?

nothing.

- How many columns of thumbnails are shown?

Doesnt matter. 1,2,3,4

BTW: I cant reproduce it for 100% sometimes it works - sometimes not.

Looks like only my win 7 bugs me. (Also the other bug with the copy from desktop...)

[ghisler(Author)]

Strange, we will have to postpone that to a later version, sorry.

[Samuel]

Could you tell me if there is some code different if you change the thumb line with a key-press?

BTW: It also happens when I press page down, page up, pos1, end and also left right. (if this results in a line change)

[ghisler(Author)]

No - this is handled by Windows, TC just gets the WM_DRAWITEM messages. Can you try to make a video with a screen cam tool to show me what happens? Maybe it gives me some clue...

[Samuel]

When I tried to record I figured out that I can only reproduce it with "Leistungsoptionen" -> "Visuelle Effekte"

- "Desktopgestaltung aktivieren"
- "visuelle Stile für Fenster und Schaltflächen aktivieren"

In English turn the Aero effects on.

My record prog wants to disable them...
