It shouldn't do that, it should play out the mate, unless I resign.

It did not do that and the game in question was a draw according to the
repetition rule:
on move 86 (reptition number 1 is 87.Kf2, then 89.Kf2, then 91.Kf2, when
making this move I should have had the option to claim a draw, then
further reptitions: 93.Kf2, 95.Kf2, 97.Kf2, 99.Kf2, only then did the
computer deviate):
8/8/8/4k3/8/4K1r1/7n/8 w
(white king on e3, black king on e5, black knight on h2, black rook
checks on g3)
86. Ke3 Rg3+
87. Kf2 Rg8
88. Ke3 Rg3+
89. Kf2 Rg7
90. Ke3 Rg3+
91. Kf2 Rg8
92. Ke3 Rg3+
93. Kf2 Rg7
94. Ke3 Rg3+
95. Kf2 Rg8
96. Ke3 Rg3+
97. Kf2 Rg7
98. Ke3 Rg3+
99. Kf2 Rg8
100. Ke3 Ng4+
101. Kf3 Kf6
102. Kf4 Nh6
103. Ke4 Rd8
104. Kf4 Rd6
105. Ke4 Nf7
106. Kf4 Kg6
107. Ke4 Ng5+
108. Kf4 Rd5
109. Ke3 Kf5
110. Kf2 Rd3
111. Ke2 Rg3
112. Kf2 Ne4+
113. Ke2 Kf4
114. Kd1 Rg2
Here the computer stopped to play, hence obviously he resigned ;).
In fact above there was not a 3-fold repetition, it was a 7-fold
repetition of the same position.
