You're experiencing exactly what I described.
I suspect you do the same thing I do when stopped at a light, which is to shift to neutral and release the clutch.

So, the gears are not moving, but the input shaft is spinning inside them because the clutch is engaged. When you disengage the clutch and select 1st, the synchro quickly matches the speed difference and causes the input shaft to stop, which causes the clunk. It doesn't matter how long you're stopped, if the clutch is engaged, then the input shaft is turning.

If you go back to neutral and release the clutch, the input shaft is again tied to the engine so it spins at engine rpm again. You should be able to repeat this and get the clunk every time without ever moving forward.
