PuTTY semi-bug scroll-button-hang

I've observed the following behaviour on a colleague's machine. I can't reproduce it myself. - JTN

PuTTY is set to paste on middle button. On this system, when the middle button is pressed, there's a chance that the Microsoft Intellipoint scroll pointer thing is activates (the pointer changes to a circle containing a dot and up/down triangles, and moving the mouse scrolls the window).

If the middle button is pressed and released quickly, there is no deletorious effect other than the appearance of this pointer.

However, if the middle button is held and then released part-way through a multi-line paste, the following occurs:

• The pasting stops dead part-way through.
• PuTTY appears to "hang" - keypresses do nothing, and the mouse pointer stays an I-beam over the title bar (normally it changes to a proper pointer).

Alt-Tabbing away unwedges PuTTY, although the missing pasted characters never come through.

Could be a bug in the way we deal with press/release events?
