summary: System tray activity breaks pointer hiding
class: bug: This is clearly an actual problem we want fixed.
priority: historic: This is an old bug report that we think is either fixed without noticing, or confined to old systems, or too vague.

Activity in the Windows system tray (new icons, possibly changed icons) can cause the pointer to become spuriously unhidden when `Hide mouse pointer when typing in a window' is checked.

We've had one report of this on Win2K (5.00.2195). I (JTN) can reliably reproduce it at work with Win2K by sending myself mail (Outlook adds an icon to the system tray when this happens).

Update, 2004-Jul-25: I was unable to reproduce the system tray behaviour on a Win98SE system, but activity in other windows would cause WM_MOUSEMOVE and WM_NCMOUSEMOVE messages to be sent when nothing had actually changed. As of tomorrow's snapshot, PuTTY will ignore such messages. Hopefully this will solve the original problem; if it works for you it'd be nice if you could tell us.

(Aside: the mouse pointer occasionally seems to get shown on my Win98SE system - as a pointer, not an I-beam - and then isn't hidden by subsequent typing. I think it may momentarily be an hourglass first. It's sometimes caused by playing a .WAV file for a bell, and sometimes happens for no apparent reason. This doesn't appear to be visible to the usual PuTTY show/hide pointer mechanisms (show_mouseptr()), so isn't fixed by the above change.)

SGT, 2024-11-17: classifying this bug as historic. It was last mentioned in 2004, and specified Win2k.
