Issue: Waveform Viewer hangs after downward temperature DC sweep

QSPICE

Simulation Context:
Temperature DC Sweep for a bandgap reference circuit.

Test Cases:

  1. .dc temp -55 125 .1
    :white_check_mark: QSPICE runs normally. Waveform Viewer opens and displays results as expected.
  2. .dc temp 125 -55 .1
    :warning: After simulation completes, the Waveform Viewer pops up but becomes unresponsive (hangs).
    :warning: Same behavior occurs when manually launching the Waveform Viewer via double-click .qraw file .

Observation:
The issue appears to be triggered by the reverse temperature sweep direction (from high to low). The simulation itself completes, but the viewer fails to render or respond.

Mike has fixed the issue.
After updating QPSICE, it will be OK.
