2497 * not be redrawn at all. Accordingly, we must not
2498 * paint any character cell in a WM_PAINT context which
2499 * already has a pending update due to terminal output.
2500 * The simplest solution to this - and many, many
2501 * thanks to Hung-Te Lin for working all this out - is
2502 * not to do any actual painting at _all_ if there's a
2503 * pending terminal update: just mark the relevant
2504 * character cells as INVALID and wait for the
2505 * scheduled full update to sort it out.
2507 * I have a suspicion this isn't the _right_ solution.
2508 * An alternative approach would be to have terminal.c
2509 * separately track what _should_ be on the terminal
2510 * screen and what _is_ on the terminal screen, and
2511 * have two completely different types of redraw (one
2512 * for full updates, which syncs the former with the
2513 * terminal itself, and one for WM_PAINT which syncs
2514 * the latter with the former); yet another possibility
2515 * would be to have the Windows front end do what the
2516 * GTK one already does, and maintain a bitmap of the
2517 * current terminal appearance so that WM_PAINT becomes
2518 * completely trivial. However, this should do for now.

4963 * situations the contents of the clipboard might not be

4965 * may block. This leads to trouble if the application
4966 * delivering the clipboard data has to get hold of it by -
4967 * for example - talking over a network connection which is
4968 * forwarded through this very PuTTY.
4970 * Hence, we spawn a subthread to read the clipboard, and do
4971 * our paste when it's finished. The thread will send a
4972 * message back to our main window when it terminates, and
4973 * that tells us it's OK to paste.
