Hello,

Since last week I have the exact same problem (never had this one in all the years using Ide before) : Ide freezes when I type a letter (It comes back to life after some time I didn't measure the time but about 20s or more ==> the poll timeout ?)

It all started when I created a new sub package for my app and directly decided to erase it (using delete form Ide menu).
Since it started on an action I rarely do: I thought some congif or tmp files were messes up, so I tried erasing all the working data in the directories but Ide would still always freeze once I type the first letter.
To make it work again I had to rename my Ide to something else in order to provoque a fresh install (and therefor new .cache and working directories).

Since this morning, Here it is again Confused

I compiled theide in debug mode (I have the lattest git version no more than a few days old) and launched in debug ==> same freeze happens !
I erased the clipboard ==> still getting freeze

Here is the backtrace I get:

Thread 1 "ide" received signal SIGINT, Interrupt.

Note the key pressed should be a 'v' or 'tab' (I may be mistaken)

I tried to get other backtraces in other conditions : I always get the same backtrace result
It seems quite strange : I type a letter, it freezes, and the backtrace points at Upp::Bar::Scan() which, at the end waits for clipboard entry ???

My exact Git version is:

Here is the code for Upp::LineEdit:1258

bool LineEdit::Key(dword key, int count) {
	NextUndo();
	switch(key) {
	case K_CTRL_UP:
		ScrollUp();
		return true;
	case K_CTRL_DOWN:
		ScrollDown();
		return true;
	case K_INSERT:
		OverWriteMode(!IsOverWriteMode());
		break;
	}
	bool sel = key & K_SHIFT;
	dorectsel = key & K_ALT;
	dword k = key & ~K_SHIFT;
	if((key & (K_SHIFT|K_ALT)) == (K_SHIFT|K_ALT))
		k &= ~K_ALT;
	switch(k) {
	case K_CTRL_LEFT:
		{
			PlaceCaret(GetPrevWord(cursor), sel);
			break;
		}
	case K_CTRL_RIGHT:
		{
			PlaceCaret(GetNextWord(cursor), sel);
			break;
		}
	case K_LEFT:
		MoveLeft(sel);
		break;
	case K_RIGHT:
		MoveRight(sel);
		break;
	case K_HOME:
		MoveHome(sel);
		break;
	case K_END:
		MoveEnd(sel);
		break;
	case K_UP:
		MoveUp(sel);
		break;
	case K_DOWN:
		MoveDown(sel);
		break;
	case K_PAGEUP:
		MovePageUp(sel);
		break;
	case K_PAGEDOWN:
		MovePageDown(sel);
		break;
	case K_CTRL_PAGEUP:
	case K_CTRL_HOME:
		MoveTextBegin(sel);
		break;
	case K_CTRL_PAGEDOWN:
	case K_CTRL_END:
		MoveTextEnd(sel);
		break;
	case K_CTRL_C:
	case K_CTRL_INSERT:
		Copy();
		break;
	case K_CTRL_A:
		SelectAll();
		break;
	default:
		dorectsel = false;
		if(IsReadOnly())
			return MenuBar::Scan(WhenBar, key);
		switch(key) {
		case K_DELETE:
			DeleteChar();
			break;
		case K_BACKSPACE:
		case K_SHIFT|K_BACKSPACE:
			Backspace();
			break;
		case K_SHIFT_TAB:
			AlignChar();
			break;
		case K_CTRL_Y:
		case K_CTRL_L:
			if(cutline) {
				CutLine();
				break;
			}
		default:
			if(InsertChar(key, count, true))
				return true;
			return MenuBar::Scan(WhenBar, key);   ******************* L1258 *******************
		}
		return true;
	}
	dorectsel = false;
	Sync();
	return true;
}

I guess InsertChar() didn't work for some reason ?

Note : all is running again ... and I didn't do anything to correct it (Assist is still running)
