Why does Dark GDK detect a nonexistant mouseclick?

My program, like any other, requires the user to click things. Unfortunately, whenever I run my game, somehow Dark GDK assumes that a mouse button has been clicked, and then it calls all of the mouseclick functions. This has gotten very frustrating and I can't figure out what the problem is. Here's what my code looks like:

if (dbMouseClick() == 1)
{
functionA();
functionB();
}

If anyone can find something wrong with this, then any help is appreciated.

Are you aware that dbMouseClick() will return results as long as you hold the button down? So even if you click really fast you may poll again before you release the button and get a second hit. You need to use a boolean flag to show that the mouse has been clicked and use that to ignore any subsequent clicks until the mouse is no longer showing clicked then set the flag to false.

best way to fix it? I'd say set a variable that's false when the mouse is 0, and when the mouse is clicked, check also that its false, and make it true in the loop.

well, my personal favorite to solve this problem is:

+ Code Snippet

int currentclick = 0;
void currentClick() {
switch(dbMouseClick()) {
	if(dbMouseClick() != 0) {
		if(currentclick == 0) {
			currentclick = dbMouseClick();
		}
		else {
			currentclick = 0;
		}
	}
	else {
		currentclick = 0;
	}
}

run the function at the start of you while ( LoopGDK ( ) ), and instead of calling dbMouseClick == x, check currentclick == x. works fine for me.

Thanks for the help, and I will definitely use a bool variable to stop dbMouseClick() from returning 1 after the mouse has been clicked once. Still, my problem is that when I start my program, even if I don't touch the mouse at all, dbMouseClick() still returns 1. To me this seems very strange. Any ideas?
